Katana is 刀, which in ordinary Japanese means sword or blade rather than one specific design. English narrowed it to the long curved sword a samurai wore edge upward through the belt, paired with the shorter wakizashi. The curve is a by-product of how it is made: the hard edge steel and softer spine cool at different rates in the quench, and the blade bends itself into shape.
Fiction gave it a physics of its own. Anime katana cut stone, steel and occasionally the concept of distance, and a swordsman is usually characterised by how fast he can clear the scabbard rather than by anything he does afterwards. That focus has a real ancestor in iaijutsu, the discipline of drawing and cutting as a single movement, which anime borrowed and then stretched well past what steel does.
The blade survives every genre change. Rurouni Kenshin gives its hero a reversed edge so he can keep an oath against killing. Afro Samurai puts it in a spaghetti western. Demon Slayer colours it by the fighter's breathing style. Space opera keeps it too, on the reasoning that a sword needs no ammunition, which is at least internally consistent.
Spelling KATANA
KATANA is six letters that alternate perfectly, consonant and vowel the whole way, with three A's and nothing else in the vowel slots. Once a single A lands you know two more positions. There is no long vowel and no doubled consonant to argue over, so this is one of the rare Japanese loanwords that is spelled exactly the way an English reader would guess.
